1. What classification of drug is Penicillin?
- A. Antiarrhythmic
- B. Anticonvulsant
- C. Antibacterial
- D. Mood stabilizer
Correct answer: C
Rationale: Penicillin is classified as an antibacterial drug, specifically used to treat bacterial infections. It works by inhibiting the growth of bacteria, making it an effective treatment for various bacterial infections. Choices A, B, and D are incorrect as Penicillin does not belong to these drug classifications. Penicillin does not have any direct effect on heart rhythm (antiarrhythmic), does not treat seizures (anticonvulsant), and is not used to stabilize mood (mood stabilizer).
2. What is an expected outcome for Lithium use in patients with bipolar disorder?
- A. Reduced risk of myocardial infarction
- B. Reduced risk of GI ulcers
- C. Decrease in respiratory distress
- D. Decreased incidence of acute manic episodes
Correct answer: D
Rationale: The correct answer is D: Decreased incidence of acute manic episodes. Lithium is commonly used to treat bipolar disorder by helping to stabilize mood and reduce the intensity and frequency of manic episodes. This leads to better overall management of the disorder. Choices A, B, and C are incorrect because lithium is not known to reduce the risk of myocardial infarction, GI ulcers, or respiratory distress in patients with bipolar disorder.
3. What is the primary action of warfarin as an anticoagulant?
- A. Prevents the formation of blood clots
- B. Dissolves existing blood clots
- C. Dilates coronary arteries
- D. Treats rhythm disturbances
Correct answer: A
Rationale: The correct answer is A: "Prevents the formation of blood clots." Warfarin acts as an anticoagulant by inhibiting the synthesis of certain clotting factors in the liver. This action reduces the blood's ability to clot, making it effective in preventing the formation of blood clots. Choice B is incorrect because warfarin does not dissolve existing blood clots; it prevents their formation. Choice C is incorrect because warfarin's primary action is not to dilate coronary arteries. Choice D is incorrect as warfarin is not used to treat rhythm disturbances, but rather to prevent clot formation.
4. A client has a new prescription for Loperamide. Which of the following instructions should the nurse include?
- A. Take the medication with a full glass of water.
- B. Avoid activities that require alertness.
- C. Increase your intake of high-fiber foods.
- D. Expect your stools to be black and tarry.
Correct answer: B
Rationale: The correct answer is B. Loperamide can cause drowsiness and dizziness, so clients should avoid activities that require alertness until they know how the medication affects them. Taking the medication with a full glass of water can help with absorption. Increasing intake of high-fiber foods is not directly related to Loperamide. Black, tarry stools are not expected side effects of this medication, so informing the client to expect this is incorrect.
5. When caring for a client with a wound infection, which action should the nurse perform first in the plan of care?
- A. Administer antibiotic medication.
- B. Obtain a wound specimen for culture.
- C. Review WBC laboratory findings.
- D. Apply a dressing to the wound.
Correct answer: B
Rationale: The priority action when caring for a client with a wound infection is to obtain a wound specimen for culture before initiating antibiotic therapy. This step is crucial to identify the specific microorganism causing the infection, allowing for targeted antibiotic treatment. Reviewing WBC laboratory findings and applying a wound dressing are important steps, but obtaining a wound specimen for culture takes precedence as it guides appropriate antibiotic therapy by identifying the causative organism.
